Explanation:
Detailed explanation-1: -The wall of an artery consists of three layers. The innermost layer, the tunica intima (also called tunica interna), is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer.
Detailed explanation-2: -The muscular walls of ventricles are thicker compared to atria as they have to pump blood out of the heart. They pump blood at a higher pressure to ensure it reaches all parts of the body.
